Abstract：According to the serious problem of deformation and destroy of weak mining roadway，rock structure and mechanical parameters and ingredient and field monitoring for deformation and destroy of roadway are proceeded. The physical experiment indicates that the roof and floor belong to weak of roadway surrounding rock instability rock mass，the reliability of bolt and bolt strength is depression and difficult to form stability and effective load bearing structure because the endogenic fracture and structural fracture of coal are development. The monitoring analysis indicates that the rock mass deformation is very big，floor protrude is very serious，the now support way can?t meet the requirement of rock mass nonlinearity and big deformation character，it must lead to support lose efficacy. Based on experiment and field monitoring，the measures for controlling deformation through comprehensive reinforcement are raised，the achievement attain significant application effect.
